Night Fision GLK001010OGXG Official Costa Ludus Night Sights Black Green Tritium Orange Ring Front Sight Green Tritium Bar Bla

The Costa Ludus sights were designed with direction from Chris Costa based on his extensive background with the United States Coast Guard and as a firearms instructor. These sights have several unique features that set them apart from other Night Fision sights. Most notably there are serrations on the front and rear sights to reduce glare. There are also serrations on the front edge of the rear sight to maximize onehanded manipulation. Costa Ludus sights include a proprietary Night Fision Perfect Dot in the front sight and a horizontal tritium bar in the rear sight. The tritium bar gives the shooter a clear distinction between the front and rear sights in low light conditions. The rear sight is also cut to maximize the target picture for fast acquisition. Our patented injection molded sleeve design not only holds our tritium vials securely in place it creates a brighter and more durable ring we call The Perfect Dot that provides maximum visibility both day and night. CNC Machined out of high quality steel. Black Nitride coating used to improve wear and corrosion resistance. Gunsmith Recommended for installation.
